Iron ore sample found is a part of banded iron ore formation. Hematite and goethite are major constituents of iron ore samples. Hematite in the ore sample occurs as specularite with inter granular micro-pore spaces. Goethite is profuse and occurs as colloform product in cavities in addition with the weaker bedding planes. Hematite and goethite

However, iron may be locked in minerals that are removed during the beneficiation of the ore, or which are inaccessible to the extraction process. Such carrier minerals could be gibbsite or ferrous dolomite (ankerite). Chemical analysis does not know about element speciation, whereas a simple peak position analysis of the XRD data tells the amount of non-extractable iron.
